Oceanhouse Media has released three new Dr. Seuss apps for the iPhone, iPod Touch and iPad to celebrate the 40th anniversary of Earth Day on Thurs., April 22nd. Theodor Geisel cared deeply about our environment and educating children about the value of caring for Mother Earth. He wrote The Lorax to help teach these beliefs.

The Lorax eBook combines the beautiful original artwork of the book with innovative features that promote reading in young children, including highlighted picture / word associations, professional narrations and custom background audio. High resolution artwork for the iPad and standard artwork for the iPhone are both included in the same app.

Oceanhouse Media has now released nine Dr. Seuss apps since late-November with many more to come in the near future. Dr. Seuss?s ABC, The Cat In The Hat and How The Grinch Stole Christmas! eBooks have all appeared on the App Store?s Top-Paid 100 chart, with Dr. Seuss?s ABC holding the number 4 position for over a week.

The Lorax eBook is available in the App Store for $3.99 (one app specially designed for both the iPhone and iPad with no additional charge), Lorax Garden children's game is $2.99 and Dr. Seuss Senders, greeting card sayings and quotes, is also $2.99.
